FIG. 2 shows details of the digital display section 7 and the analog display section 8, and this display section is composed of liquid crystal, light emitting diode elements, or the like. The digital display section 7 is indicated by 7a to 7d, including a segment type four-digit number display section 7a located approximately in the center, two digits and three digits of this number display section 7a.
From the colon display section 7b between the digits, the "AL" and "DUAL" display section 7c above the number display section 7a, and the two-digit number display section 7d below the number display section 7a. It is configured. The analog display section 8 is composed of 12 hour displays 8a for specifying the hour unit and 60 minute displays 8b including thick display units at 5-minute intervals, all of which are circular in shape. Arranged in equal parts.

In such a configuration, binary counter 16 is typically in a reset state (i.e., has an output on
The output signal d is output from the display switching control section 14, and the time information of the counting section 3 is sent to the decoder via the AND gate 17a and the OR gate 18a.
The digital display section 7
As shown in Figure A, the hours and minutes are displayed as 10:30 on the numerical display section 7a and the colon display section 7b, and the seconds are displayed as 30 seconds on the numerical display section 7d, so that the time is 10:25. Display 30 seconds. At this time counter 15
If the count value is "0", the display switching control section 14 outputs the output signal a, and the time information of the counting section 3 is given to the decoder/driver 6 via the AND gate 17d and the OR gate 18b. As shown in FIG. 3A, the analog display section 8 displays the hour display 8a at the 10 o'clock position, and also displays the minute display 8b from 0 to 25 minutes.

Then, when the function selection switch _S1 is operated, the count value of the counter 15 becomes "1" and the display switching control section 1
4, the output signal b is given to the AND gate 17e (the output signal d remains unchanged), and the alarm time information from the alarm time counter 10 is sent to the decoder via the AND gate 17e and the OR gate 18b.
Enter driver 6. As a result, as shown in FIG. 3B, the analog display section 8 energizes only the hour display 8a indicating 1 o'clock and the minute display 8b indicating 30 minutes to indicate the alarm time of 1:30. indicate. At the same time, "AL" is activated to notify that alarm information is included.

Further, when the function selection switch _S1 is operated to set the count value of the counter 15 to "2", the output signal c is output (the output signal d does not change), the AND gate 17f is opened, and the separate clock 9 is changed to the separate clock. Time information enters the decoder driver 6. As a result, as shown in FIG. 3C, the analog display section 8 displays, for example,
A separate clock 9 is energized with an hour display 8a indicating the hour and a minute display 8b (indicating 25 minutes) from 0 to 25 minutes.
Displays that the time being counted is 7:25. At the same time, "DUAL" is activated to notify that a separate clock time is being displayed.

In addition, the time adjustment or setting of the alarm time is performed by operating the switch _S2 to set the binary counter 16 (the state in which there is an output at the Q terminal), and the counter 15 is set to the count value "0". If switch S ₂ is operated while the counter 1 is maintained, the display status changes from A to D in Figure 3
When the counter 5 maintains the count value "1", the counter 15 further changes to the count value "2" from FIG. 3B to E.
, the display state is changed to C to F in FIG. 3, respectively.

That is, when the switch _S2 is operated and the binary counter 16 is set, the display switching control section 14 outputs a signal h, and this signal h is sent to the counter 15.
Since it is not affected by the count value of , the time information from the counter 3 is given to the decoder/driver 6 via the AND gate 17d and displayed on the analog display section 8, and this time display is as shown in FIG. D,
There is no change in either E or F. That is,
While the time display on the digital display section 7 is not changed when the binary counter 16 is in the reset state, the time display on the analog display section 8 is not changed when the binary counter 16 is in the set state.

Therefore, when the switch _S2 is operated when the count value of the counter 15 is "0", the binary counter 16
is in a set state, the output signal e is output from the display switching control section 14, and time information is input to the decoder/driver 5 via the AND gate 17a. In this case _, although there is no substantial change in _FIG . Corrections will be made.

Further, when the count value is "1", the output signal f is applied to the AND gate 17b and alarm time information is input to the decoder driver 5. Then, as shown in FIG. 3E, the digital display section 7 energizes its number display section 7a and colon display section 7b, "AL". As a result, alarm time 1
30 minutes will be displayed.

When the count value is "2", the output signal g is given to the AND gate 17c, so that the separate clock time information is displayed on the digital display section 7 via the decoder/driver 5, as shown in FIG. 3F. The section 7 energizes the number display sections 7a and 7d, the colon display section 7b, and "DUAL", respectively. As a result, a separate clock time of 7:25:30 is displayed. In the case of E and F of FIG. 3 as well, the signals f and g are applied to the correction circuit 13, so that the alarm time can be set and the time of another clock can be adjusted using the switches _S3 and _S4 .

In this way, when displaying functional information other than time information, only one of the analog display section 8 or the digital display section 7 is displayed, and the other displays the normal time as is, so both You can view information at the same time, which is very convenient. In addition, since the time is adjusted while the time information is displayed on the digital display section 7, it is easy to accurately read the time information to be set or adjusted, and the time can be set or adjusted quickly. be able to. moreover,
The current time is always displayed, so for example,
If you want to set an alarm in 30 minutes, all you have to do is look at the current time and set the alarm to the current time plus 30 minutes.
In this case, only the hour unit can be set according to the time difference, and the minutes can be set according to the current time, making it easy to set the separate clock 9.

Note that in the above embodiment, the analog display section 8
, it can only display 12 hours, but “AM” and “PM”
A display may be provided so that morning and afternoon can be identified. Furthermore, it goes without saying that the alarm time display or dual time display (separate clock time display) may be replaced by a timer time display, stopwatch time display, or the like. In addition, the digital display section 7
Information such as the date, day of the week, month, year, etc. may be displayed or additionally displayed. Of course,
These pieces of information may be displayed in hours, minutes, and seconds.

In addition, in this embodiment, the analog display section displays other functions in the normal state, and the digital display section 7 displays other functions when making corrections or settings, but the display section to which the display is switched can be used as desired. However, the display section that is switched and displayed may be changed depending on the function, for example, in a normal state, alarm information is switched and displayed on the analog display section, and stopwatch information is switched and displayed on the digital display section.

As described in detail above, the present invention comprises: a timekeeping function means 3 which obtains current time information by counting clock pulses of a predetermined cycle; a plurality of additional function means 9 which each obtain function information different from the time information; 1
0, a digital display section 7 that digitally displays each information obtained by these functional means, an analog display section 8 that displays analog information, and an external operation switch _S1 . It has function specifying means S ₁ and 15 for sequentially selecting and specifying the information of which function means is to be displayed, and an external operation switch S _2.

Since the configuration is equipped with correction means S ₃ , S ₄ , 13 for correcting the contents of the data by operating the correction digit selection switch and correction switch, it is possible to accurately read the current time on the digital display and read the current time on the analog display. It is possible to read the time at a specific time, and the display of additional function information other than the current time does not impair the original function of the watch, which always displays the current time, depending on the function or the user's preference. This can be done on either digital or analog display sections. Furthermore, display switching between the digital display and analog display can be performed simply by operating the external operation switch _S2 , so the display switching operation is extremely simple.
Therefore, if the additional function is a timer, for example, where accurate time information is required only near the end of measurement, and it is desirable to be able to easily check rough time information at other times, Extremely effective display can be performed. Furthermore, since the initial information for the timekeeping function means and the additional function means is set or corrected when the function information is digitally displayed, it is easy to accurately read the information to be set or corrected. ,
It also has the effect that setting and modifying information such as time and time can be performed in a short time.
